Water-circulating floor-cleaning vehicle

Abstract

The invention provides a water-circulating floor-cleaning vehicle, and relates to the field of cleaning appliances, in particular to a floor-cleaning appliance. The water-circulating floor-cleaning vehicle comprises a vehicle frame, a water tank, an electric brush disk, a vacuum pump, a connecting tube, a wiper, a water pump and a filter, wherein the water tank and the vacuum pump are arranged in the vehicle frame; the vacuum pump is communicated with the water tank; the electric brush disk is arranged below the front part of the vehicle frame; the wiper is arranged below the back part of the vehicle frame; the filter is arranged at the water inlet end of the water tank; the filter is communicated with the wiper; the water outlet end of the water tank is connected with the water pump; the water outlet of the water pump is communicated with the water inlet of the electric brush disk. According to the water-circulating floor-cleaning vehicle, sewage left after floor cleaning is refilled into the water tank after being collected and filtered, and is used for cleaning a floor. The problem of low efficiency caused by high water consumption, large size of the water tank and the need of frequent water refilling and change existing in the prior art is solved; meanwhile, in the water-circulating floor-cleaning vehicle, a sewage tank and a corresponding water level monitoring device in the water tank are removed, so that cost is saved.

Description

technical field [0001] The invention relates to the field of cleaning instruments, in particular to a floor washing vehicle. Background technique [0002] As a daily service and cleaning tool, floor washing machines are widely used in hotels, hotels and other service industries, as well as in many public places, such as hospitals, airports, stations, buildings, squares, etc. Floor washing vehicles are favored by consumers due to their high cleaning efficiency and reduced labor intensity of cleaning personnel. [0003] At present, most of the washing machines are composed of a vehicle frame, a clean water tank, a sewage tank, a brush plate, a sewage reclaimer and several motors. This kind of floor washing machine can meet the needs of daily floor cleaning, but it uses the combination of clean water tank and sewage tank, the disadvantages are: [0004] In the work, in order to meet the requirement of a long continuous working time, the capacity of the two water tanks must be...

AI Technical Summary

Problems solved by technology

[0004] In the work, in order to meet the requirement of a long continuous working time, the capacity of the two water tanks must be large enough to hold more water to meet the requirements, resulting in the overall volume of the washing machine having to increase, thus making the washing machine Increased weight, increased battery power consumption, and reduced use time;

[0005] In order to protect the vacuum pump, a water level monitoring device must be installed in the sewage tank to prevent the sewage water level from reaching the exhaust port of the sewage tank, causing water to be sucked into the vacuum pump and causing damage, and the cost will increase accordingly;

[0006] At the same time, the water tank cannot be enlarged indefinitely, so it is necessary to add water and discharge sewage many times when cleaning a site with a relatively large area, which makes the work efficiency not high;

[0007] However, the pollution level of the sewage after washing is not high every time. In many cases, the ground of hotels, buildings, airports, etc. is not particularly dirty, and the pollution level of sewage is not high. It is obvious that the clean water is discarded after one washing. It is a waste of water, so that the water consumption of one operation is high, especially in today's water shortage
